The furniture system of Andrea Ponsi is disarmingly simple, so simple that it makes one say, “how come I didn’t think of that?’ The main elements consist of a tube and a joint. The tube is connected with the joint, thus becoming the basis of any object to be completed later by other elements, either suggested by the designer or purposely defined by the taste of the person who is assembling it. Given these relative connections, even the connected relatives are content. The examples published within this book have a considerable feature: they are aesthetically correct. They have the right dimensions, perfect orientation, are pleasant on the whole, and functionable. What more could you ask for ?...
— Bruno Munari, from the introduction of "Design Elementare"

copper system “T”

The generating principle to any project is the line, its organizing element is the joint and its completion is the surface. The line breaks up into two directions by means of the joint; two lines became one by means of the joint. The joint is both a finishing and a static point, but also, one of rotation, allowing the line to move through space. Together with the joint, the line builds an object, developing rhythm and geometric forms. Through pure geometric shapes such as the triangle, square and circle, the forms evolve and transform. Thus, spatial symbols or expressions of physical lows, abstract images and figurations are created. The initial project expands and new constructive models begin, almost autonomously, to reproduce themselves. Research therefore becomes the metaphor of an endless story, a journey of countless possibilities for discovery.
